These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Seasonal Rot: The third season got left out of the recent marathons on the Sci-Fi Channel and Chiller. With good reason.
Special Effect Failure: Claymuppet dinosaurs, blindingly mismatched green-screen transfers, yetis wrapped in shag carpeting, and a unicorn with a chinstrap, among many, many other examples. The Dopey puppet was a particularly bad example.
Crowning Moment of Awesome: For the movie: Near the end of the film Rick Marshall gets eaten by the T. rex. It would not be surprising if there were spontaneous cheers in theatres during this scene. Alternatively, when Doctor Marshal pulls a Big Damn Heroes moment by riding in on said T. rex probably made the other half of the audience cheer.
Rick and Holly becoming a couple, considering she was his daughter in the show. Particularly squicky when he gives her a compliment at one point that makes no sense except as something a father would say to a daughter.
Then again, at times Will and Holly's relationship in the original series had some incestuous overtones. This Troper recalls in ep. 2 how, when trapped by Sleestaks and hanging in a net, Will touches his sister's cheek, looks in her eyes like a lover and tell her how brave she is. I was all, "Oh, hell, no".
